IMPROVEMENT IN STREET-Learners.

Be it known that we, Jon): I, An-m1 and W.- L. NICHOLS, both of Norwich, in the county of New London, and State of iC-onnecticnt, have invented acertain new-andnseful Improvement on Street and other Lanterns, of which the following is a full, ciear, and exact description,reference being had to the accompanying drawing, forming part of this specification, and in which Figure 1 represents an outside elevation of a street-lantern constructed according to our improvement; and

Figure 2,1 ertical section of the same.

Like letters indicate like parts in both figures.

.Tlie nature of our invention consists in providing or constructing the glazed frame of the-lantern with tuhnlarpassages, so arrnnged' as that they supply the, lantern with the air necessary for cornbustion, without exposing the flame to he waited or extinguished by the wind And it-furthcr consists in so constructing the sevcrelglated sections or parts with double frames, formed with grooves. for the reception of a rope or cord packing, which answers not only to make the lantern air-tight-at' the edges of the panes, but formsa soft seat for the glass which is clamped between the double frames by means of set or adjusting-screws uniting said frames.

' Referring to the accompanying drawing, A represents'theouter main frame-or skeleton of the lantern, B its base, and C its ventilator at top. The lower p ortions of the sides of the frame A are made to form tubes 6 for a heightcorrespomling tothctdp-of the flame, or thereabouts, or-indepndeht tubes, simllarlyopen top and bottom, may be provided. These tubes, 6, serveto-isuppiy the frame with the air necessary for combustiomand are preferably arranged opposite'to each other up the corners or edges of the lantern, so that and by reason of their height relatively to the flame, opposite incoming currents of air, impinging on the flame at or nea'nits top, will have little or no wafting or extinguishing effect on it. Thus arranged, too, thctubes cast no shade nor interfere with the light of the lantern. D E are independent inner and enter panc-holding frames, fitting ageinst and within the several sections or divisions of the main frame, designed to be glazed,including the lid or door. The one of these double frames in the several sections is formed with a groovc or grooves, e, in it, in which is arranged a soft rope or cord packing (1, that on insertion may be temporarily held to its place by shellac, but which is afterwards secured bythc clamping of the two frames together, with the pnnec in between them, by means of adjustin -screws f. This rope or packing runs all round the pane in each section ordlvision, thereby not only forming" a soft bed for the glass, to the prerention of fracturc,, but an air or wind-tight joint to thepanes to the steadying of the flame, and which gives to the lanternan air-tight character.

What we claim as our invention, and dcsire'to secure-by Letter Patent, is- 1. The combination, with the lantern-head or frame, of air-tubes 6, arranged forsupply of air to theflamc, substantially as specified. p

2. The independent 'frames D E, in combination with the rope or cord packing d, arranged to fit a. groove, 0, in the one frame, and clamped or held together to hold the pane in between them, essentially as herein set forth. 7 I
